This is a multipart blog article series where I am going to explain the concepts of shell scripting and how to write a shell script in Linux, UNIX or Mac based systems. You can also follow this tutorial blog using windows but for that you have to install a bash from.

In this article we will see about select loop in shell scripting and how it is used.

  • The syntax of select loop
    select <variable_name> in list 
    do 
      command1
      command2
      commandN
    done
    
  • The list item will be denoted by different numbers, and to select any specific item from that list you have to enter that number.
  • Its structure is similar to for loop but the functionality is different.
  • It will iterate over the list and give us the menu structure.
  • We use select loop with case conditions, because in select loop we give choice to the user and in case condition we perform some task based to some choices
